Re: Ninja 250 These bikes are manufactured and delivered with very lean carburetion. Too lean to run well and be pleasant for the rider... The answer is a simple readily-available DynoJet jet kit. Costing $69 bucks, you get the bike carbureted like it's the 1970s again, ie. nice and sweet. Every Ninja 250 built needs one. They will then run better, cooler, last longer and be much more pleasant to own - and easy to start and keep running. This is just the bone-stock bike! If you change the air filtration (ie. K&N) or mount a slip-on pipe etc, your bike can become completely unstartable and even more miserable. The DynoJet kit is designed to work with K&N airbox replacement filter, which you clean and maintain and no longer disgard into landfill like the stock paper filters. If every Ninja 250 had a K&N and the jet kit, the world would be a much better place. DynoJet 2193, Parts Canada #134984 + K&N KA-2508, Parts Canada #152478 Regards
Heyy, I got a question for you, and hopefully you have an answer for me I have a 09 kawi ninja 250r, the issue that I have is when I start the bike with choke it's all fine but as soon as I leave my drive way and hit a stop sign...the bike stalls and turns off (choke is turned off). But then I turn the choke on and it runs fine...so should inreally be riding with choke on for sometime so it won't stall and turn off? Or is there a problem with my bike? Looking forward to hear back from you. Cheers, Toxic
